Pokemon Emerald with Pokesav?

I have tried to open a saved game from Pokemon Emerald that was made with No$Gba in POKESAV.
Pokesav errors each time I try to open the file. Any ideas?
Posesav version 0.38b
No$Gba version 2.4f

you can change the NDS backup media as followed to play the game

I'm not sure what you meant, did you mean to post instructions?

So wait what emulator are you trying to open it with now? if you are trying to open a save file with like Visual Boy Advance you need to go into file>>import>>battery file>> find the save with no$gba i think you have to use load snapshot, im not very sure
